490Tells @@RXVT_NAME@@ to embed its windows into an already-existing window,
491which enables applications to easily embed a terminal.
492
493Right now, @@RXVT_NAME@@ will first unmap/map the specified window, so it
494shouldn't be a top-level window. @@RXVT_NAME@@ will also reconfigure it
495quite a bit, so don't expect it to keep some specific state. It's best to
496create an extra subwindow for @@RXVT_NAME@@ and leave it alone.
497
498The window will not be destroyed when @@RXVT_NAME@@ exits.
499
500It might be useful to know that @@RXVT_NAME@@ will not close file
501descriptors passed to it (except for stdin/out/err, of course), so you
502can use file descriptors to communicate with the programs within the
503terminal. This works regardless of whether the C<-embed> option was used or
504not.
505
506Here is a short Gtk2-perl snippet that illustrates how this option can be
507used (a longer example is in F<doc/embed>):
508
509 my $rxvt = new Gtk2::Socket;
510 $rxvt->signal_connect_after (realize => sub {
511 my $xid = $_[0]->window->get_xid;
512 system "@@RXVT_NAME@@ -embed $xid &";
513 });

516
517Tells @@RXVT_NAME@@ NOT to execute any commands or create a new pty/tty
518pair but instead use the given file descriptor as the tty master. This is
519useful if you want to drive @@RXVT_NAME@@ as a generic terminal emulator
520without having to run a program within it.
521
522If this switch is given, @@RXVT_NAME@@ will not create any utmp/wtmp
523entries and will not tinker with pty/tty permissions - you have to do that
524yourself if you want that.
525
526As an extremely special case, specifying C<-1> will completely suppress
527pty/tty operations, which is probably only useful in conjunction with some
528perl extension that manages the terminal.
529
530Here is a example in perl that illustrates how this option can be used (a
531longer example is in F<doc/pty-fd>):
532
533 use IO::Pty;
534 use Fcntl;
535
536 my $pty = new IO::Pty;
537 fcntl $pty, F_SETFD, 0; # clear close-on-exec

803omitted. This resource is only available when compiled with 1146
804KEYSYM_RESOURCE. 1147The format of I<sym> is "I<(modifiers-)key>", where I<modifiers> can be
1148any combination of B<ISOLevel3>, B<AppKeypad>, B<Control>, B<NumLock>,
1149B<Shift>, B<Meta>, B<Lock>, B<Mod1>, B<Mod2>, B<Mod3>, B<Mod4>, B<Mod5>,
1150and the abbreviated B<I>, B<K>, B<C>, B<N>, B<S>, B<M>, B<A>, B<L>, B<1>,
1151B<2>, B<3>, B<4>, B<5>.
1152
1153The B<NumLock>, B<Meta> and B<ISOLevel3> modifiers are usually aliased to
1154whatever modifier the NumLock key, Meta/Alt keys or ISO Level3 Shift/AltGr
1155keys are being mapped. B<AppKeypad> is a synthetic modifier mapped to the
1156current application keymap mode state.
1157
1158The spellings of I<key> can be obtained by using B<xev>(1) command or
1159searching keysym macros from B</usr/X11R6/include/X11/keysymdef.h> and
1160omitting the prefix B<XK_>. Alternatively you can specify I<key> by its hex
1161keysym value (B<0x0000 - 0xFFFF>). Note that the lookup of I<sym>s is not
1162performed in an exact manner; however, the closest match is assured.
1163
1164I<string> may contain escape values (C<\n>: newline, C<\000>: octal
1165number), see RESOURCES in C<man 7 X> for further details.
1166
1167You can define a range of keysyms in one shot by providing a I<string>
1168with pattern B<list/PREFIX/MIDDLE/SUFFIX>, where the delimiter `/'
1169should be a character not used by the strings.
1170
1171Its usage can be demonstrated by an example:
1172
1173 URxvt.keysym.M-C-0x61: list|\033<|abc|>
1174
1175The above line is equivalent to the following three lines:
1176
1177 URxvt.keysym.Meta-Control-0x61: \033<a>
1178 URxvt.keysym.Meta-Control-0x62: \033<b>
1179 URxvt.keysym.Meta-Control-0x63: \033<c>
1180
1181If I<string> takes the form of C<command:STRING>, the specified B<STRING>
1182is interpreted and executed as @@RXVT_NAME@@'s control sequence. For
1183example the following means "change the current locale to C<zh_CN.GBK>
1184when Control-Meta-c is being pressed":
1185
1186 URxvt.keysym.M-C-c: command:\033]701;zh_CN.GBK\007
1187
1188If I<string> takes the form C<perl:STRING>, then the specified B<STRING>
1189is passed to the C<on_user_command> perl handler. See the @@RXVT_NAME@@perl(3)
1190manpage. For example, the F<selection> extension (activated via
1191C<@@RXVT_NAME@@ -pe selection>) listens for C<selection:rot13> events:
1192
1193 URxvt.keysym.M-C-c: perl:selection:rot13
1194
1195Due the the large number of modifier combinations, a defined key mapping
1196will match if I<at least> the specified identifiers are being set, and
1197no other key mappings with those and more bits are being defined. That
1198means that defining a key map for C<a> will automatically provide
1199definitions for C<Meta-a>, C<Shift-a> and so on, unless some of those are defined
1200mappings themselves.
1201
1202Unfortunately, this will override built-in key mappings. For example
1203if you overwrite the C<Insert> key you will disable @@RXVT_NAME@@'s
1204C<Shift-Insert> mapping. To re-enable that, you can poke "holes" into the
1205user-defined keymap using the C<builtin:> replacement:
1206
1207 URxvt.keysym.Insert: <my insert key sequence>
1208 URxvt.keysym.S-Insert: builtin:
1209
1210The first line defines a mapping for C<Insert> and I<any> combination
1211of modifiers. The second line re-establishes the default mapping for
1212C<Shift-Insert>.
1213
1214The following example will map Control-Meta-1 and Control-Meta-2 to
1215the fonts C<suxuseuro> and C<9x15bold>, so you can have some limited
1216font-switching at runtime:
1217
1218 URxvt.keysym.M-C-1: command:\033]50;suxuseuro\007
1219 URxvt.keysym.M-C-2: command:\033]50;9x15bold\007
1220
1221Other things are possible, e.g. resizing (see @@RXVT_NAME@@(7) for more
1222info):
1223
1224 URxvt.keysym.M-C-3: command:\033[8;25;80t
1225 URxvt.keysym.M-C-4: command:\033[8;48;110t

1230
1231Comma-separated list(s) of perl extension scripts (default: C<default>) to
1232use in this terminal instance; option B<-pe>.
1233
1234Extension names can be prefixed with a C<-> sign to prohibit using
1235them. This can be useful to selectively disable some extensions loaded
1236by default, or specified via the C<perl-ext-common> resource. For
1237example, C<default,-selection> will use all the default extension except
1238C<selection>.
1239
1240Extension names can also be followed by an argument in angle brackets
1241(e.g. C<< searchable-scrollback<M-s> >>, which binds the hotkey for
1242searchable scrollback to Alt/Meta-s). Mentioning the same extension
1243multiple times with different arguments will pass multiple arguments to
1244the extension.
1245
1246Each extension is looked up in the library directories, loaded if
1247necessary, and bound to the current terminal instance.
1248
1249If both of these resources are the empty string, then the perl
1250interpreter will not be initialized. The idea behind two options is that
1251B<perl-ext-common> will be used for extensions that should be available to
1252all instances, while B<perl-ext> is used for specific instances.

1494
1495 index_88 = (r * 4 + g) * 4 + b + 16 # r, g, b = 0..3
1496 index_256 = (r * 16 + g) * 16 + b + 16 # r, g, b = 0..15

1519=head2 ALPHA CHANNEL SUPPORT
1520
1521If Xft support has been compiled in and as long as Xft/Xrender/X don't get
1522their act together, rxvt-unicode will do it's own alpha channel management:
1523
1524You can prefix any colour with an opaqueness percentage enclosed in
1525brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
1526(0-100) that specifies the opacity of the colour, where C<0> is completely
1527transparent and C<100> is completely opaque. For example, C<[50]red> is a
1528half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1529is the recommended format to specify transparency values, and works with
1530all ways to specify a colour.
1531
1532For complete control, rxvt-unicode also supports
1533C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
1534specifications, where the additional C<aaaa> component specifies opacity
1535(alpha) values. The minimum value of C<0000> is completely transparent,
1536while C<ffff> is completely opaque). The two example colours from
1537earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
1538C<rgba:0000/ff00/0000/f332>.
1539
1540You probably need to specify B<"-depth 32">, too, to force a visual with
1541alpha channels, and have the luck that your X-server uses ARGB pixel
1542layout, as X is far from just supporting ARGB visuals out of the box, and
1543rxvt-unicode just fudges around.
1544
1545For example, the following selects an almost completely transparent black
1546background, and an almost opaque pink foreground:
1547
1548 @@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
1549
1550When not using a background image, then the interpretation of the
1551alpha channel is up to your compositing manager (most interpret it as
1552transparency of course).
1553
1554When using a background pixmap or pseudo-transparency, then the background
1555colour will always behave as if it were completely transparent (so the
1556background image shows instead), regardless of how it was specified, while
1557other colours will either be transparent as specified (the background
1558image will show through) on servers supporting the RENDER extension, or
1559fully opaque on servers not supporting the RENDER EXTENSION.
1560
1561Please note that due to bugs in Xft, specifying alpha values might result
1562in garbage being displayed when the X-server does not support the RENDER
1563extension.
